The F10 M5 and F13 M6 are very similar cars. They have the exact same transmissions (manual / DCT) and motor (560 horsepower S63TU). Car and Driver compares these two cars in the video below. Some interesting comments from Car and Driver such as calling the M6 a 911 and Nissan GT-R rival which it really isn't. The M6 is much more of a grand touring car than either of those and just because it has a comparable amount of horsepower does not make it a direct rival.

Car and Driver also states the M5 is a hell of a lot cheaper than the M6. Somewhat misleading, these are both $100k+ cars when all is said and done although the M6 base price does start at $106,100 versus $89,900 for the M5. Hell of a lot cheaper? Neither is cheap and the difference becomes negligible with options at this price level. The M5 certainly is no bargain.

These two cars are pretty much the same thing. The M6 has a lower center of gravity and is slightly lighter at 4088 pounds versus 4313 pounds for the F10 M5. That is really what the difference between the two comes down to. Less weight means the M6 edges the M5 in acceleration at 8.5 seconds to 100 mph versus 8.7 for the M5. It also runs through the 1/4 mile at 2 MPH higher at 124 versus 122 for the M5. Keep in mind the cars were not tested on a drag strip so those trap speeds are likely inflated.

The M6 is not surprisingly also better on the track. It hit a higher peak speed and was quicker through every sector. The difference is minor just as in acceleration but the M6 is the better performer of the two. If one wants the absolute best performance, the M6 is the choice. If one wants four doors, the M5 is the choice. They both perform admirably.

M5 -- Ultimate family sedan. It can be civil when you want (reasonable gas mileage for the HP you're getting, DCT trans, full comfy interior & seating for 5), and a Race Car when you wanna show off (560 HP/500 TQ, 0-60 in ~4.5 seconds, will prob get under 4 once some quality aftermarket parts & tuning become more available).

I hit 0-60 in under 4 with the M3 at the strip. The issue isn't power, it's traction.

Doing the math, the M6 is 20% more expensive than the M5, and 6% lighter. So I think the authors of the original article are right by saying the M5 is a hell of a lot cheaper, but I'm not sure the weight difference is a lot. But...the M6 looks much better and so it must be more expensive If I were in the market for a high-end M car, I would go for the M6 Gran Coupe, even if it's more expensive than both of these.

guys you cant compare a new price to a used price, if you compare the m6 to a cl63 at over 160k its a bargain!! a 911tt is also over 150 as well, now go back a couple of model years and sure the price goes down

IDK guys...These base prices are mind boggling. I think I have a pretty good job. These cars are getting flat out unattainable. Economy is in the toilet. And sure, we're talking about cars that are far beyond a plain old nice family sedan. But, 6 figures for something that is intended to be a daily driver? No comprende. I can't understand how everything is selling so well.
